This snowflake is relatively big (around 4 millimeters from tip to tip), with simple shape, but complex inner pattern (especially at arms). If you look closely at this crystal, you may notice that it slightly resembles triangular snowflakes: like these snow crystals, it have hexagonal symmetry, but with interleaving shorter / longer sides of central hexagon. In this case, however, triangular structure is hardly noticeable.

Also, you can find small and simple plate crystal at surface of bigger one, and this tiny companion also have triangular structure, with three shorter and three longer sides. This is strange and beautiful couple, in my opinion.
